8 Foods Even The Experts Won’t Eat

Food scientists are shedding light on items loaded with toxins and chemicals–and simple swaps for a cleaner diet and super-sized health. Experts from different areas of speciality explain why they won’t eat these eight foods.
Clean eating means choosing fruits, vegetables, and meats that are raised, grown, and sold with minimal processing. Often they’re organic, and rarely (if ever) should they contain additives. But in some cases, the methods of today’s food producers are neither clean nor sustainable. The result is damage to our health, the environment, or both. So we decided to take a fresh look at food through the eyes of the people who spend their lives uncovering what’s safe–or not–to eat. ” Their answers don’t necessarily make up a “banned foods” list. But reaching for the suggested alternatives might bring you better health–and peace of mind.

1. The Endocrinologist Won’t Eat: Canned Tomatoes

Fredrick Vom Saal, is an endocrinologist at the University of Missouri who studies bisphenol-A.
The problem: The resin linings of tin cans contain bisphenol-A, a synthetic estrogen that has been linked to ailments ranging from reproductive problems to heart disease, diabetes, and obesity. Unfortunately, acidity (a prominent characteristic of tomatoes) causes BPA to leach into your food. Studies show that the BPA in most people’s body exceeds the amount that suppresses sperm production or causes chromosomal damage to the eggs of animals. “You can get 50 mcg of BPA per liter out of a tomato can, and that’s a level that is going to impact people, particularly the young,” says vom Saal. “I won’t go near canned tomatoes.”
The solution: Choose tomatoes in glass bottles (which do not need resin linings), such as the brands Bionaturae and Coluccio. You can also get several types in Tetra Pak boxes, like Trader Joe’s and Pomi. Exposure to BPA Causes Permanent Damage In OffSpring

2. The Farmer Won’t Eat: Corn-Fed Beef

Joel Salatin is co-owner of Polyface Farms and author of half a dozen books on sustainable farming.The problem: Cattle evolved to eat grass, not grains. But farmers today feed their animals corn and soybeans, which fatten up the animals faster for slaughter. But more money for cattle farmers (and lower prices at the grocery store) means a lot less nutrition for us. A recent comprehensive study conducted by the USDA and researchers from Clemson University found that compared with corn-fed beef, grass-fed beef is higher in beta-carotene, vitamin E, omega-3s, conjugated linoleic acid (CLA), calcium, magnesium, and potassium; lower in inflammatory omega-6s; and lower in saturated fats that have been linked to heart disease. “We need to respect the fact that cows are herbivores, and that does not mean feeding them corn and chicken manure,” says Salatin.
The solution: Buy grass-fed beef, which can be found at specialty grocers, farmers markets, and nationally at Whole Foods. It’s usually labeled because it demands a premium, but if you don’t see it, ask your butcher.

3. The Toxicologist Won’t Eat: Microwave Popcorn

Olga Naidenko, is a senior scientist for the Environmental Working Group.

The problem: Chemicals, including perfluorooctanoic acid (PFOA), in the lining of the bag, are part of a class of compounds that may be linked to infertility in humans, according to a recent study from UCLA. In animal testing, the chemicals cause liver, testicular, and pancreatic cancer. Studies show that microwaving causes the chemicals to vaporize–and migrate into your popcorn. “They stay in your body for years and accumulate there,” says Naidenko, which is why researchers worry that levels in humans could approach the amounts causing cancers in laboratory animals. DuPont and other manufacturers have promised to phase out PFOA by 2015 under a voluntary EPA plan, but millions of bags of popcorn will be sold between now and then.
The solution: Pop organic kernels the old-fashioned way: in a skillet. For flavorings, you can add real butter or dried seasonings, such as dillweed, vegetable flakes, or soup mix. Make it organic and use coconut oil. If You’re Still Eating Microwave Popcorn, You’re Not Fully Grasping The Health Consequences

4. The Farm Director Won’t Eat: Nonorganic Potatoes

Jeffrey Moyer is the chair of the National Organic Standards Board.

The problem: Root vegetables absorb herbicides, pesticides, and fungicides that wind up in soil. In the case of potatoes–the nation’s most popular vegetable–they’re treated with fungicides during the growing season, then sprayed with herbicides to kill off the fibrous vines before harvesting. After they’re dug up, the potatoes are treated yet again to prevent them from sprouting. “Try this experiment: Buy a conventional potato in a store, and try to get it to sprout. It won’t,” says Moyer, who is also farm director of the Rodale Institute (also owned by Rodale Inc., the publisher of Prevention). “I’ve talked with potato growers who say point-blank they would never eat the potatoes they sell. They have separate plots where they grow potatoes for themselves without all the chemicals.”

The solution: Buy organic potatoes. Washing isn’t good enough if you’re trying to remove chemicals that have been absorbed into the flesh. Budget tip: Organic potatoes are only $1 to $2 a pound, slightly more expensive than conventional spuds.
5. The Fisheries Expert Won’t Eat: Farmed Salmon
Dr. David Carpenter, director of the Institute for Health and the Environment at the University at Albany, published a major study in the journal Science on contamination in fish.
The problem: Nature didn’t intend for salmon to be crammed into pens and fed soy, poultry litter, and hydrolyzed chicken feathers. As a result, farmed salmon is lower in vitamin D and higher in contaminants, including carcinogens, PCBs, brominated flame retardants, and pesticides such as dioxin and DDT. According to Carpenter, the most contaminated fish come from Northern Europe, which can be found on American menus. “You could eat one of these salmon dinners every 5 months without increasing your risk of cancer,” says Carpenter, whose 2004 fish contamination study got broad media attention. “It’s that bad.” Preliminary science has also linked DDT to diabetes and obesity, but some nutritionists believe the benefits of omega-3s outweigh the risks. There is also concern about the high level of antibiotics and pesticides used to treat these fish. When you eat farmed salmon, you get dosed with the same drugs and chemicals.
The solution: Switch to wild-caught Alaska salmon. If the package says fresh Atlantic, it’s farmed. There are no commercial fisheries left for wild Atlantic salmon. Farmed Fish vs. Wild Fish: How Healthy

6. The Cancer Researcher Won’t Drink: Milk Produced With Artificial Hormones

Rick North is project director of the Campaign for Safe Food at the Oregon Physicians for Social Responsibility and former CEO of the Oregon division of the American Cancer Society.

The problem: Milk producers treat their dairy cattle with recombinant bovine growth hormone (rBGH or rBST, as it is also known) to boost milk production. But rBGH also increases udder infections and even pus in the milk. It also leads to higher levels of a hormone called insulin-like growth factor in milk. In people, high levels of IGF-1 may contribute to breast, prostate, and colon cancers. “When the government approved rBGH, it was thought that IGF-1 from milk would be broken down in the human digestive tract,” says North. “There’s not 100 percent proof that this is increasing cancer in humans,” admits North. “However, it’s banned in most industrialized countries.”
The solution: Buy raw milk or check labels for rBGH-free, rBST-free, produced without artificial hormones, or organic milk. These phrases indicate rBGH-free products. Why Do Humans Still Drink Milk?

7. The Biotech Specialist Who Won’t Eat Conventional Soy: GMO Unfermented Soy

Michael Harris is biotech specialist who has directed several projects within the biotech sector including those for genetically engineered food. He has been a consultant, manager and director for companies such as Xenon Pharmaceuticals and Genon Corporation.

The problem: Genetically engineered food is a cause of great concern due to the manipulation of DNA and genetic code including transfers from one species to another. Fermented Soy Is The Only Soy Food Fit for Human Consumption and since almost 90% of soy in the world is genetically modified, if you are not ensuring sources are organic, long-term health problems are inevitable, especially since soy has been found to affect hormonal balance and even cause cancer.
The solution: Check labels to ensure soy is Non-GMO or organic and never consume unfermented sources. If possible contact the company to find out exactly where the Non-GMO soy was obtained.

8. The Organic-Foods Expert Won’t Eat: Conventional Apples

Mark Kastel, a former executive for agribusiness, is codirector of the Cornucopia Institute, a farm-policy research group that supports organic foods.
The problem: If fall fruits held a “most doused in pesticides contest,” apples would win. Why? They are individually grafted (descended from a single tree) so that each variety maintains its distinctive flavor. As such, apples don’t develop resistance to pests and are sprayed frequently. The industry maintains that these residues are not harmful. But Kastel counters that it’s just common sense to minimize exposure by avoiding the most doused produce, like apples. “Farm workers have higher rates of many cancers,” he says. And increasing numbers of studies are starting to link a higher body burden of pesticides (from all sources) with Parkinson’s disease.
The solution:Buy organic apples or apples from a farmer that you trust!

Microwave Dangers: What You Need To Know

The first time I became skeptical of microwave ovens was when I conducted a small experiment by myself comparing the growth of plants (from seedlings) watered with regular distilled water vs. water that had been microwaved. Much to my surprise those plants that had been watered with microwaved water did not grow, or grew very poorly. Those watered with distilled water flourished, just as the rest of the plants in my house normally had. This experiment has not only been confirmed by myself, but many others as well (a simple google search will bring up numerous reports of microwaved water being quite un-suiting to grow plants with).

So what happens to the water when it is microwaved? If such an effect occurs with plants, then why are we consuming foods that are microwaved? Can our bodies even utilize the nutrients in foods that have been microwaved?

A microwave oven creates radio waves at frequencies of around 2.45 GHz. As with other wave types, a radio wave is a type of electromagnetic radiation. When matter is heated in the microwave the atoms and molecules vibrate quickly to generate kinetic energy (or heat), such as they would on the stove or in the oven. The only difference here is that microwaves have very strong electric fields. Electric fields have the ability to stretch molecules, as well as separate their charges so that the atoms lose an electron (ionization).

Electric fields in microwave ovens cause electric current to flow into food, which then has the ability to rearrange the atoms in your food, changing the molecular structure (ionization). This is one of the reasons why microwave ovens have the capability to destroy essential nutrients in your food as compared to cooking on the stove. Ionizing (displacing single electrons) is what has the ability to form free radicals in your food. Free radicals are harmful to our body and one of the major culprits in cancer formation.

Microwaved meats cause the formation of d-Nitrosodienthanolamines (1), a well-known carcinogen, as well as turning plant alkaloids from microwaved vegetables into carcinogenic matter that should not be consumed by humans (or any animal for that matter). In addition, microwaves lower nutrient content of foods by as much as 60 to 90% – in a study by Russian researchers, they found that there was marked decrease in the bio-availability of vitamin B complex, vitamin C, vitamin E, essential minerals and lipotropic factors in microwaved foods. Another study published in November 2003 found that microwaved broccoli in a little bit of water lost up to 97% of its beneficial antioxidants compared to steamed broccoli (stove-top) which lost only 11% antioxidants (2).

In 1992, Richard Quan and colleagues took freshly frozen human milk samples and microwaved them for over 30 seconds at different temperatures. They found that the milk heated at high temperatures (98ºC) had lost nearly all of it’s resistance to contamination, and when exposed to E.coli, became infected 18 times faster than unheated breast milk. Even milk heated at low temperatures (25ºC) had a chance at becoming infected five times faster by E.coli than unheated breast milk (3).

In 1989, Dr. Hans-Ulrich Hertel, a Swiss food scientist conducted a study to examine and research the effects of microwaved food on humans. He recruited nine people, including himself, and alternately exposed them to microwaved and conventionally cooked food from organic sources. Before consuming these foods, a sample of blood was drawn, as well as at certain intervals after eating.
They found that after microwaved food consumption there was a dramatic reduction of all blood hemoglobin and cholesterol values (both good (HDL) and bad (LDL)), and that LDL cholesterol levels were slightly more elevated relative to HDL cholesterol levels. In addition, lymphocyte (white blood cell) activity was considerably reduced after ingesting microwaved foods, compared to foods that had been conventionally cooked. When the blood of those who consumed microwaved foods was exposed to bacteria, the bacteria flourished, whereas blood from those who did not consume microwaved foods had much lower bacterial count. This suggests that the energy from microwaved foods has the ability to be passed onto those who consume the food (4).
